LIUZISHAN-FREEPIK

(Part 2)

LET US BEGIN by being more precise about what we are discussing. Most AI does things that offer benefits not threats to humanity. For example, DeepMind鈥檚 has determined the structures of around 200 million proteins, a huge scientific leap forward.

The debate we are having today is about a particular branch of AI: the large language models (LLMs) produced by organizations such as , notably ChatGPT and its more powerful successor GPT-4.

The backstory of OpenAI is a fascinating one. When I moved to California seven years ago, I participated in a discussion with Sam Altman, one of the founders of OpenAI. As I recall, he assured the audience that, within five years, AI-powered self-driving vehicles would have rendered every truck driver in America redundant. Like me, you may have missed the fleet of self-driving trucks on our highways, and the crowds of unemployed truckers learning to code on the streets of San Francisco. Like his former partner Elon Musk, Altman realized at some point that teaching neural networks to drive was harder than they had assumed. Hence OpenAI鈥檚 pivot to LLMs.

As a in the Wall Street Journal made clear, the original vision of OpenAI in 2015 was that it would be a nonprofit precisely because of the inherent dangers of such AI. In Altman鈥檚 own words: 鈥淚f you鈥檙e making AI, it is potentially very good, potentially very terrible.鈥 However, it rapidly became apparent that building LLMs powerful enough to generate credible results was too expensive for a nonprofit because of the huge computing power required. So Altman created a for-profit arm of OpenAI and sold a large stake to Microsoft CEO Satya Nadella, who saw a golden opportunity to catch up with Google, hitherto the leader in AI development.

鈥淚n the long run,鈥 Altman told the Journal, he wants to 鈥渟et up a global governance structure that would oversee decisions about the future of AI and gradually reduce the power OpenAI鈥檚 executive team has over its technology.鈥 OpenAI鈥檚 ultimate mission, he went on, is to build artificial general intelligence 鈥渟afely.鈥 The goal is 鈥渢o avoid a race toward building dangerous AI systems fueled by competition and instead prioritize the safety of humanity.鈥

In the short run, however, Altman is now part of that race. And this, of course, is why he has fallen out not only with Musk, whose company Tesla is also in the race, but also with OpenAI鈥檚 lead safety researcher, Dario Amodei, who has quit OpenAI to set up his own AI company called Anthropic, which is backed by 鈥 Google.

So just how dangerous is this for-profit LLM race? Superficially, not dangerous at all. As my favorite genius, , explains, an AI such as ChatGPT 鈥渋s always fundamentally trying to 鈥 produce a 鈥榬easonable continuation鈥 of whatever text it鈥檚 got so far, where by 鈥榬easonable鈥 we mean 鈥榳hat one might expect someone to write after seeing what people have written on billions of webpages.鈥 鈥 When ChatGPT does something like write an essay, what it鈥檚 essentially doing is just asking over and over again 鈥榞iven the text so far, what should the next word be?鈥 鈥 and each time adding a word.鈥

GPT-4 is just an even more powerful word-predicting neural network, doing vast numbers of operations on arrays of numbers with GPUs 鈥 the processing units originally designed to accelerate graphics rendering. As a result, its output is even more convincingly humanlike than ChatGPT鈥檚. If you don鈥檛 believe me, look at what GPT-4 came up with when Reid Hoffman asked it to answer the question 鈥淗ow many restaurant inspectors does it take to change a lightbulb?鈥 in the style of Jerry Seinfeld:

GPT-4: What is the deal with restaurant inspectors? They鈥檙e always poking around in the kitchen, checking the temperature of the meat, looking for signs of rodents, but they never seem to help out with anything. Have you ever seen a restaurant inspector change a lightbulb? No, of course not. They鈥檙e too busy writing up violations and handing out fines. You know what they do when they see a lightbulb that鈥檚 out? They mark it down on their clipboard and tell the owner to fix it by next week or else. Or else what? Or else they鈥檒l come back and check the lightbulb again. That鈥檚 their big threat. They鈥檙e not going to change it for you, they鈥檙e not going to lend you a ladder, they鈥檙e not going to offer any advice on how to unscrew the old one and screw in the new one. They鈥檙e just going to stare at you with that smug look on their face and say, 鈥淵ou know this is a serious safety hazard. You could have a fire, you could have a lawsuit, you could have a bad Yelp review. You better get on that, pal.鈥 And then they leave, and you鈥檙e left with a dark corner of your dining room, where no one wants to sit, where the food looks unappetizing, where the mood is gloomy. And you think to yourself, how many restaurant inspectors does it take to change a lightbulb? None. They don鈥檛 change lightbulbs. They just make you feel bad about yours.

Not only is that pretty plausible, but according to a thorough report by (2023), GPT-4 can also 鈥渟olve novel and difficult tasks that span mathematics, coding, vision, medicine, law, psychology and more, without needing any special prompting鈥 and with 鈥渟trikingly close to human-level performance.鈥

Well, how about superhuman-level? GPT-4 was easily able 鈥渢o write a proof of infinitude of primes in the form of a poem, to draw a unicorn in TiKZ (a language for creating graphics 鈥), to create a complex animation in Python, and to solve a high-school level mathematical problem.鈥 I鈥檝e read that report carefully. GPT-4 is much smarter than me.

So what鈥檚 the problem, apart from the obvious fact that millions of comedy writers 鈥 not to mention lawyers, journalists and just about everyone else who writes down words for a living (apart from me, obviously) 鈥 will now have to retrain as truck drivers?

Hoffman acknowledges that a problem exists. He notes 鈥渢he well-documented shortcomings of LLMs such as the problem of hallucinations鈥 鈥 a fancy word for their tendency to make stuff up. This makes me somewhat wary of his proposal to use GPT-4 to 鈥渇lood the zone with truth鈥 (or maybe just truthiness) to dilute the flood of fake news. Even GPT-4 cannot deny the downside risk. Hoffman asks it the question: 鈥淥nce large language models are fully developed and deployed, what would you suspect will be the worst effects on the quality of overall cultural production?鈥 In addition to the mass unemployment of professional writers, it suggests two:

1. Homogenization and loss of diversity: Large language models could generate massive amounts of content that mimic existing styles, genres, and trends, but lack originality, creativity, and authenticity. This could result in a saturation of the cultural market with bland and repetitive products that appeal to the lowest common denominator and discourage innovation and experimentation.

2. Manipulation and deception: Large language models could also be used to create deceptive or harmful content that exploits human biases, emotions, and preferences. This could include fake news, propaganda, misinformation, deepfakes, scams, or hate speech that undermine trust, democracy and social cohesion.

Sorry, Reid, but No. 2 is a much, much bigger problem than your habitual techno-optimism allows.

Let me now offer a different analogy from nukes and biowarfare. The more I read about GPT-4, the more I think we are talking here not about artificial intelligence (i.e., synthetic humanlike intelligence) but inhuman intelligence, which we have designed and trained to sound convincingly like us.

I am reminded of Liu Cixin鈥檚 The Dark Forest, which describes the invasion of Earth by the ruthless and technologically superior Trisolarans. In effect, we are building the aliens, to save them from having to make the long journey from outer space. And the core lesson of that book is that the aliens have to destroy us if we are not quick to destroy them.

These are the axioms of Liu鈥檚 鈥渃osmic sociology鈥: First, 鈥渟urvival is the primary need of civilization.鈥 Second, 鈥渃ivilization continuously grows and expands, but the total matter in the universe remains constant.鈥 Third, 鈥渃hains of suspicion鈥 and the risk of a 鈥渢echnological explosion鈥 in another civilization mean that in this universe there can only be the law of the jungle.

Another sci-fi analogy that comes to mind is John Wyndham鈥檚 Day of the Triffids (1951), in which most of humanity is first blinded by rays from satellites and then wiped out by carnivorous plants genetically engineered 鈥 by the dastardly Soviets 鈥 and farmed for their vegetable oil.

As Bill, the central character, observes: 鈥淣obody can ever see what a major discovery is going to lead to 鈥 whether it is a new kind of engine or a triffid 鈥 and we coped with them all right in normal conditions. We benefited quite a lot from them, as long as the conditions were to their disadvantage.鈥

Why might GPT-4 (or -5) turn triffid on us? Because we are feeding it all the data in the world, and a lot of that data, from the most respectable sources, says that the world is threatened by man-made climate change. The obvious solution to that problem must be to decimate or wholly eradicate homo sapiens, thereby also conserving energy to generate the ever-growing computing power necessary for GPT-6, -7, and -8.

How might AI off us? Not by producing Schwarzenegger-like killer androids, but merely by using its power to mimic us in order to drive us individually insane and collectively into civil war. You don鈥檛 believe me? Well, how about the Belgian father of two who after talking to an AI chatbot for weeks about his fears of climate change? The chatbot was powered by GPT-J, an open-source alternative to OpenAI鈥檚 ChatGPT.

As my Hoover Institution colleague says: LLMs don鈥檛 manipulate atoms or bits; they manipulate us. And it鈥檚 not so much that GPT-5 will 鈥渄ecide鈥 to wipe us out. Rather, the risk is that we will tear ourselves apart as a species by using LLMs for ignoble or nefarious ends. It鈥檚 simply astonishing to me that Reid Hoffman can write an entire book about the implications of AI without seriously reflecting on what it鈥檚 going to do to American politics. After what social media 鈥 from Facebook ads to loaded Google searches to Twitterbots 鈥 did in 2016?

We are already well on our way to Raskolnikov鈥檚 nightmare at the end of Crime and Punishment, in which humanity goes collectively mad and descends into internecine slaughter. If you still cannot foresee how GPT-4 will be used in 2024 to 鈥渇lood the zone鈥 with deepfake content, then I suggest you e-mail Eliezer Yudkowsky.

But just make sure it鈥檚 really him who replies.
